- Execute the diff by running /opt/open-xchange/sbin/listconfigdiff
- by default folder /opt/open-xchange/bundles is used to get original configuration files and /opt/open-xchange/etc is used for installed configuration files
- you can change the default by using the option -o, -i or --original, --installed
- '-h' will also give you the information
- with -f or --file you are able to define a file in which the output of the diff will be written

The output of the tool shows:
- differences in file occurrences below the defined folders (additional files, missing files, duplicate files)
- additional files that are no configuration files
- differences (changes values, missing properties, additional properties, ...) for all file types marked as configuration file (properties, yaml, yml, conf, cnf, ccf, xml, sh, perfMap, types, no extension)
- each configuration file type has its own implementation how to compare original and installed configuration file
- critical properties such as keys or passwords are obscured
